by passages or aisles terminating in a diagonal arch. The arches between these aisles and the western semi-dome are pierced, and thus isolate the western dome piers. On the south the church has been greatly altered ; for the entire southern semi-dome and the southern bay of the narthex have been removed and replaced by three aisles of two bays each. These bays are equal in height, and are covered by cross - groined vaults with strong transverse pointed arches supported on square piers, the whole forming a large hall held up by two piers, and showing the distinct influence of Italian Gothic work. This part of the building is modern. On the eastern wall is a large picture of the Last Judgment.
The plan of this church may be compared with that of S. Nicholas Methana (Fig. 97).
